No propping is required.

Only a 40mm leveling screed is required over the slab.

Echo Prestress may be specified with cantilevers by incorporating reinforcing into the hollow cores which are grouted in the factory during the casting process.

Where Echo Prestress is used as roof slabs or balconies, a minimum Ref. 100 mesh is required in the insulating screed over the panels, as well as a slip joint on the walls. On indoor areas where tiles are specified a minimum Ref. 100 mesh is required in the screed. Expansion joints are required in tiled areas. All unfinished areas also require the same mesh. Refer to the detailed screeding specifications.
